Earth Hour is a global event organized by WWF (World Wide Fund for Nature, also known as World Wildlife Fund) and is held on the last Saturday of March annually, asking households and businesses to turn off their non-essential lights and other electrical appliances for one hour to raise awareness towards the need to take action on climate change. Earth Hour also is known to result in drop of energy consumption. But not one power generating station has reported lowered production of energy. Statistically, this relates to a zero effect on change of carbon emissions.

Earth Hour started in 2007 in Sydney, Australia with 2.2 million homes and businesses turning their lights off for one hour. Only a year later and this event had become a global sustainability movement with up to 50 million people across 35 countries participating. Global landmarks such as the Golden Gate Bridge in San Francisco, Rome’s Colosseum and the Coca Cola billboard in Times Square, all stood in darkness, as symbols of hope for a cause that grows more urgent by the hour.

Earth Hour 2010 is a global call to action to every individual, every business and every community. A call to stand up, to take responsibility and to get involved in working towards a sustainable future. Iconic buildings and landmarks from Europe to The Americas will stand in darkness. People across the world will turn off their lights and join together in creating the vital conversation about the future of our precious planet.

Over 64 countries and territories are participating in Earth Hour 2010. This number grows every day as people realise how such a simple act, can have such a profound result in affecting change.

In Indonesia, EarthHour Program 2010 had saved electricity until 811 MW (for system in Java and Bali) or Rp. 580 Million (http://arsipberita.com/show/bisnis/finance/2010/03/28/earth-hour-sukses-pln-jawa-bali-berhemat-rp-580-juta/). So, more participant will get more saving.

Earth Hour is a message of hope and a message of action. Everyone can make a difference.
